Summary of averaged intensity of immunostaining for the α2-AR (alpha-2 adrenergic receptor) in the human cornea and retina
| Tissue | Layer | α2-AR staining |
|---|---|---|
| These are the averaged data from all images collected in the current study. Intensity of the human tissue staining was graded, with − representing no staining; + representing low or weak staining; ++ representing moderate or intermediate staining; and +++ representing high or strong levels of staining. | ||
